GUSTAVE F. S'EXAUER, OF LA CEOSSE, WISCONSIN; ASSIGNOR TO BADGER CORRUGATING COMPANY, A CORPORATION OF WISCONSIN.

CUPOLA.

Specification of Letters Patent.

Application filed. July 8, 1919. Serial No. 309,287.

To all whom it may concern:

Be it known that L, GUsTavn F. SEXAUER a citizen of the United States, resident of La Crosse, Wisconsin, have invented certain new and useful Improvements in Cupolas, of which the following is a specifica tion.

The invention is a cupola for ventilating buildings, such as barns or other farm buildings and one object of the invention is to provide a cupola which may be readily assembled and which may be erected on the building with a minimum expenditure of time and labor, by a person of ordinary Tn the accompanying drawings Figure I is a perspective view of the base section of a cupola complete as put in place on the building.

Fig. 2 is a perspective view of the inner frame of the base in place at the opening in the roof but with the walls of the base omitted.

Fig. 3 is a vertical sectional view of a portion of the cupola base.

Fig. lis a horizontal I sectional view through the outer casing.

In carrying out my invention I make the base of an outer casing and an inner frame portion which are so constructed that they will fit together without possibility of error and capable of being erected quickly and with little labor.

This cupola base is adapted to receive upon it any suitable form of top portion, which preferably fits down around the upstanding flange a of the base.

The base is built up with an outside casing and an interior frame. The function of this interior frame is to strengthen the base and to provide the means by which it may be attached to the roof of the building.

The interior frame is made up of an upper member 1 consisting of heavy galvanized bars set up on edge and providing in the present case a rectangular open frame member. It has secured thereto heavy gal vanized steel straps or standards 2, which at their lower ends have holes 2 punched therein to receive nails or screws for securing the frame to the header at the opening in the roof, and the frame is shown erected in Fig. 1. The rectangular upper portion is braced by the angularly positioned corner members 3, and the same rivets at 3 which hold these braces at end serve also to secure the straps or standards 2 to the upper frame bars.. These upper frame bars are tapped with holes at 4: to receive screws for holding the flange the'frame bars. The flange a is an upstand-' ing one and lies against the outer face of the frame bar 1 and the fastening screws may be inserted from the outside of the base through the flange (1 of the casing and into the tapped holes 4 of the frame bars.

Thisconstruction avoids the necessity of the workman getting inside the cupola in order to fasten the parts together. The steel inner frame strengthens the outer casing and forms means of ready connection between this casing and the roof structure.

If the. opening in the roof structure is not provided with headers adapted to receive the lower ends of the straps or standards flatwise as 'shown,' these straps orstandards can be given a twist intermediate of their'length so that their lower portions will stand at right angles to their upper parts and thus be in position for lying flat against the rafters to which they maybe screwed or nailed.

The outer casing is made up of galvanized steel sides 8, a molding 6, corner 7 and on two sides there are flashing members 9 provided with flanges 9 for securing the base to the roof. At the top of the casing there is an upstanding flange a'made up of three thicknesses of metal and reinforced by the frame bars I to which the flange is secured.

This flange a is made up of the upper edge of the side 8, and the upper edge of the molding which is doubled upon itself and embraces the upper edge of the side 8.

The holding screws pass through the flange a into the tapped holes a in the frame bar I.

The molding at its lower edge is secured to the side 8 by tongues 6 on the molding passing through openings in the side plate and clenched.

The molding not only adds to the appearance of the cupola base but gives strength and rigidity thereto. The parts of the base are held together without nails rivets or other fastenings thus avoiding perforating these parts and leaving them in condition to be weather proof.

I prefer to assemble the base and interior frame at the factory so that it may be Patented Dec. 30, 1919. I

a of the casing to shipped as one body and handled and erected as one body, as shown in Fig. 1.

In Fig. 1 the dotted lines at X indicate that the side is to be cut out at its lower edge to fit the roof.

1. A base for a cupola having an outer casing, a frame within the same comprising an upper member fastened to the upper portion of the casing and extending around the Wall thereof and standards connected to said upper member extending down therefrom and attachable to the roof, substantially as described.

2. A base for acupola having an outer casing with an upstanding flange, an inner frame member comprising bars arranged up on edge, and against which the upstanding flange lies, means securing said flange to the bars and standards of strap metal extending down from the bars and punched with openings by which the standards may be nailed to the roof, substantially as described.

3. In combination, bars forming an open frame, braces at the corners of the frame, standards extending down from the frame and having openings by which they may be nailed to the roof and an outer casing secured to the frame, substantially as described.-

4. In combination, an inner frame, and an outer casing having a top flange of several thicknesses secured to the frame, said casing comprising a molding and sides extending up back of the molding, said molding interlocking with the sides, substantially as described.

5. In a cupola base, the combination of a casing having sides, a molding extending around the upper part of the sides and having an upstanding doubled flange embracing the upper edge of the sides, and a frame within the casing having a bar standing on edge lying against the said doubled flange, means for securing together the bar and the three thicknesses of metal formed by the doubled flange and the edge of the side, and standards depending from the upper frame bar, substantially as described.

6. In combination in a cupola base, a frame, a casing secured at its upper edge to the frame, said casing comprising sides, a.

molding extending around the sides at the upper part thereof and secured thereto, corner members and flashing members secured to said sides without screws or the like, two of the sides being free from the flashing and cut out to fit the roof, substantially as de scribed.

In testimony whereof I affix my signature.
